I was invited to Prochownia by a friend of mine who lives nearby. I was not aware of the fact that there are such relaxed, green places to have a coffee in this part of town. Of course, there are Żywiciel and Głodomory but Prochownia has sweeter circumstances around (tables and boxes outside, surrounded by brick walls, lots of green and monuments). The drinks and food are lovely (check their delicious m&m’s chocolate cheesecake) and reasonably priced (aperol spritz for 15 PLN in town is a good price indeed).
Prochownia is a small cafe / snack restaurant situated in Żeromski Park, designed in 1932 by Polish architects Leon Danielewicz and Stanisław Zadora-Życieński. The park uses former military buildings in the area (also have a look at the Cytadela article, another military area in the surroundings).
Prochownia seems to be children-friendly, dog-friendly and generally friendly towards all people coming to visit. The lovely surroundings (walls of military fortifications and lots of green) make it a great place to rest & relax.
Check their Kino letnie (Summer cinema) offer.
